Do Magnetic, or Electric, or Electromagnetic fields, actually exist .
The following thread on another site reminded me of what I often wonder, do fields interact .
https://physics.stackexchange.com/questions/471007/why-dont-electromagnetic-waves-interact-with-each-otherNOTE - I was sure that recently, or in the last 6 months, I had seen an article about an experiment using very powerful lasers that showed that when the paths of 2 lasers met, that the path of one or both lasers was deflected . I can not find that experiment now .
- I assume there are also 'Electromagnetic-Lasers', whose beam behaves like an electromagnet, that would be better than the experiment below, for the electromagnetic-field at least .

A Simple Experiment
The diagrams below show a simple experiment, which I have no way of doing .
( NOTE - I forgot to add a diagram for Electric-Fields / Electrets )
- Two permanent-magnets ( or electromagnets in the other diagram ) ARE OUT OF LINE OF SIGHT OF EACH OTHER, the line of sight between them is blocked by a block that completely blocks their fields, however, above the block, their fields can meet .
( 1 ) - For Magnetic-Fields, could you cause one magnet to move by moving the other magnet in this set-up ?
( 2 ) - For Electric-Fields, could you cause one electret to move by moving the other electret in this set-up ?
( 3 ) - And stupidly I will also ask, for Electromagnetic-Fields, could you cause one electromagnet to move by moving the other electromagnet in this set-up ?
If the answer to ( 1 ) or ( 2 ) or ( 3 ) is 'no interaction', then could it be that what we interpret as fields, may actually be something like QUANTUM-ENTANGLEMENT, some sort of unknown connection between two objects or sub-atomic-particles having similar properties, maybe their interactions are warps in space-time or gravity or something .

Deflecting Radio Transmission
- Can radio signals / transmission be blocked just by using a radio-beam to deflect another radio-beam before it is received by the receiver, as in the diagrams attached below, when everything is out of line of sight of each other ( of course in practice this would be stupid, since a lot would still get through ) .
Note - The block, blocking 100% of the fields in the diagrams below, could maybe be made out of a weak magnet, or out of many small weak magnets .
